Just curious how much bump steer you guys are getting when you set up your rack with 2 1/2" arms. |

I used to run the latest rage, the rack and pinion set up, and it sucked, it bout broke my arms, my hands, everytime i hit a rock, a rut, or anything. I used to complain about it all the time, thats how much bump steer i was getting. Thats why i took the rack out, and i put a GM power steering setup on. now i love it, i can even ride through the creek bed, holding a beer in one hand and steering with the other. |

| Post subject: | Bump steer explanation |
There seems to be a missunderstanding with a lot of guys what Bump Steer actually is. It has nothing to do with steering feed back when you hit rocks ruts etc. It is how much Toe in and Toe out of the front tires you get thru the supensions full travel. What happens if you have to much Bump steer the buggy will follow the path of what ever wheel is on the ground first off of a jump in rough terrain etc. In a fast turn the outside tire tends to get light or actually come off the ground. The inside tire will now direct the buggy in what ever direction it is toed. The key is to set up the rack when you weld it on to minimize the amout of toe change. I just got thru welding mine on today and at full droop I have about 3/16" and at full compression I have about 1/4". I probably could have gotten less however that last little bit takes a lot of screwing around and is not really worth it for general Woods riding. I just like to get as little as possible because of the speeds I run the Woods at. Its better to have less at full droop then at full compression. The trick is to limit the amout of tow in the part of the travel that is used the most. Sorry to get a little long winded. |

The redneck dictionary defines bump steer as "When you hit a rock, your vehical turns and you spill your beer" |

Who needs steering when you have cutting brakes right Dean. Can't steer when its in the air with the wheels anyways. LOL!! The Wild Kids |

Steve 1" to 2" is way to much and I can see why you were not happy with it. It was not set up right. It takes some screwing around to get the rack in the right place. I bolted mine to a piece of steel shelving angle iron and clamped it to the beam so I could move it around untill I got it where I wanted it then welded it in place. Im looking at a total of 9/16" bump steer. Did you have a steering damper on it? Racks do give you a lot more feedback then a steering box mostly due to the gear ratios and that standard steering boxs use right angle worm gears. Its a lot easyer to move a rack from the load end because its a rack and pinion gear with little resistance. Dean dont worry about it you don't have bump steer you have slop steer and a smoke screen to hide all of the pinball effect you get lol. |

I got rid of my steering wheel feedback by changing the offset of my wheels to the stock offset. My bump steer is 3/8". |

I agree with Odyknuck in some ways, bumpsteer in my book is where the damn steering wheel takes off and it damn near breaks my thumb! I am currently running a Saco rack with billet racing struts and chromoly heim joints on each end. I am going to run a torque generator with Howe's power steering pump and PSC reservoir. The only time I have trouble with steering is when the front tires (either side) hits a stump and/or a big rock, it wants to grab the tire and fold it in like you steered it all the way left or right. It is proven to run this setup to eliminate this problem unless you want to play the steering game (hand on wheel tight, other on cutter brakes, and think about the wheel could take off from your hand at any second) they say that you can put your finger in the steering wheel hole and go up a hill and not worry about a thing. |

Well Badvw your whole explanation has nothing to do with Bumpsteer. What you described is steering feedback please re-read my description. I will say that when you go to power steering your feedback will be almost eliminated and power steering will not cure Bumpsteer. Bumpsteer is in the geometry of the mechanics of the steering setup. |

I understand your description, I'm just saying in a Redneck way of bumpsteer just like everybody else has been saying. I just love to have power steering just for the fact it is nice to have! Sorry for any inconvience I may have cause you.  Oh, by the way, I just want to say that this ain't NASCAR like we are splitting hairs. LOL You are a smart guy by the way.

No inconvience, just trying to share a little knowledge so guys here understand. After all thats what this forum is for to help one another to learn. BTW I am putting power steering on my new buggy just so I can eliminate the "Feedback". Sorry I could not help myself.

I have learned, the hard way, not to put my thumbs in the spokes of the wheel. There is also a solid steering wheel that will stop this from happening. There is nothing wrong with power steering, but it is just something that can go wrong. If you need it then get it. But if your buggy drives fine and all you want to stop is sore thumbs bolt this steering wheel on and your problem is solved. One less thing to break. If you have large front tires and need it to control you buggy then get it. http://www.speedwaymotors.com/p/2057,18 ... ng%20wheel |

Power steering is the way to go. Theres just something about being able to palm the steering wheel thru the Woods with your other hand on the Cutter brakes or the shifter. I watched plumberbill do that and he just zips thru the woods effortlessly while im spinning my wheel back and forth with both hands to keep up. It just wears me I tell ya lol. |
